Salttech

At Salttech, we specialize in Dyvar®, a one-step concentration and crystallization process combining robust evaporation with integrated crystallization capabilities. We offer clients a value-creating, scalable, and proven solution for concentration of complex brines, with the possibility of (fractional) crystallization. Our technology achieves high water recovery while minimizing operational issues such as corrosion and clogging.

Dyvar® Technology offers a proven and modular solution for reducing or dewatering disposal (brine or evaporation) pond volumes, recovering water, supporting extraction processes and removing salts, particularly where conventional technologies, and natural evaporation ponds fall short.

Mining processes often result in highly contaminated, complex wastewater with hypersaline brines. These complex brines, generated from extraction processes, return water flows, pollution control dams, or general mining-impacted waters, are increasingly subject to environmental regulation and disposal challenges. Long-term brine management can also be significant in mine-closure planning.

Why mining operators choose Dyvar®

• High water recovery (MLD to ZLD) reducing brine volume

• Operates with complex brines (containing organics, low/high pH, high TDS)

• Removes primary salts

• Enables f.e. a higher lithium concentration for extraction processes

• Enables compliance with environmental regulations
